Browser.triple click selects paragraph
From MozillaZine Knowledge Base
This preference lets you select the containing paragraph when triple-clicking instead of selecting the current line.
Possible values and their effects
Select the current paragraph on triple-click (Default on trunk builds after 2005-08-10).
Select the current line on triple-click.
A number of bugs with the implementation means that until recently (2005-08-10 on trunk), this feature often had unexpected/undesired results. Itâ€™s not worth setting the preference to true on earlier versions of the browser.
